Definitions
- the present invention relates to heat-curable reaction resin mixtures containing polyepoxides, polyisocyanates, a cyanoacetamide compound as a reaction accelerator, and, if appropriate, fillers and / or conventional additives and the use of cyanoacetyl compounds as hardeners for such reaction mixtures.
- reaction accelerators for reaction resin mixtures of polyepoxides and polyisocyanates EP / IC resins
- EP: IC molar ratio of 1 to 5 tertiary amines and imidazoles and onium salts of tertiary amines and imidazoles addition complexes of Boron trihalides with tertiary amines and imidazoles or with tertiary amines and imidazoles deactivated with electron acceptors can be used.
- EP-A 130,454 the BF3 and BCl complexes of n-octyldimethylamine and of benzyldimethylamine and further 7,7,8,8-tetracyanoquinodimethane / 1-cyanoethyl-2-phenyl- are as hardeners for such EP / IC resins Imidazole specifically listed as a representative of a deactivated imidazole accelerator.
- DE-OS 3,323,153 amines especially tert.
- Amines and imidazoles are described as particularly suitable reaction accelerators for special EP / IC resins which, as an additional epoxy resin component, have polyoxyalkylene glycol polyglycidyl ethers to improve the thermomechanical properties of the resins.
- DE-OS 2,846,123 cyanoacetic acid esters and amides are known as hardeners for epoxy resins in the heat.
- the reactive resin systems which contain boron halide / amine complexes as reaction accelerators, have poor moisture resistance.
- highly corrosive gases such as HCl and HF can form through hydrolysis of the corresponding boron halides, which is disadvantageous for use in the field of electrical engineering and electronics.
- the reactive systems according to the invention preferably contain as epoxy resins a) polyepoxide compounds, in particular those made from aliphatic, cycloaliphatic or aromatic epoxides or mixtures thereof.
- epoxy resins are suitable as epoxy resins a), such as, for example, those which have groups of the formula II bonded directly to oxygen, nitrogen or sulfur atoms wherein either R6 and R8 each represent a hydrogen atom, in which case R7 then represents a hydrogen atom or a methyl group, or R6 and R8 together represent -CH2CH2- or -CH2CH2CH2-, in which case R7 then represents a hydrogen atom.
- polyglycidyl and poly ( ⁇ -methylglycidyl) esters which can be obtained by reacting a compound containing two or more carboxylic acid groups per molecule with epichlorohydrin, glycerol dichlorohydrin or ⁇ -methylepichlorohydrin in the presence of alkali.
- Such polyglycidyl esters can be derived from aliphatic polycarboxylic acids, for example oxalic acid, succinic acid, glutaric acid, adipic acid, pimelic acid, suberic acid, azelaic acid, sebacic acid or dimerized or trimerized linoleic acid, from cycloali derived phatic polycarboxylic acids such as tetrahydrophthalic acid, 4-methyltetrahydrophthalic acid, hexahydrophthalic acid and 4-methylhexahydrophthalic acid and from aromatic polycarboxylic acids such as phthalic acid, isophthalic acid and terephthalic acid.

Abstract
Description
- Die vorliegende Erfindung betrifft hitzehärtbare Reaktionsharzmischungen enthaltend Polyepoxide, Polyisocyanate, eine Cyanacetamidverbindung als Reaktionsbeschleuniger, sowie gegebenenfalls Füllstoffe und/oder übliche Additive und die Verwendung von Cyanacetylverbindungen als Härter für solche Reaktionsmischungen.
- Aus der DE-OS 3,323,084 ist bekannt, dass als Reaktions-Beschleuniger für Reaktionsharzmischungen aus Polyepoxiden und Polyisocyanaten EP/IC-Harze) mit einem Ansatzmolverhältnis EP:IC von 1 bis 5 tertiäre Amine und Imidazole sowie Oniumsalze von tertiären Aminen und Imidazolen, Additionskomplexe von Bortrihalogeniden mit tertiären Aminen und Imidazolen oder mit Elektronenakkzeptoren desaktivierte tertiäre Amine und Imidazole verwendet werden.
- In der EP-A 130,454 sind als Härter für solche EP/IC-Harze die BF₃- und BCl-Komplexe von n-Octyldimethylamin sowie von Benzyldimethylamin und weiter 7,7,8,8-Tetracyanochinodimethan/1-Cyanethyl-2-Phenyl-Imidazol als Vertreter eines desaktivierten Imidazol-Beschleunigers spezifisch aufgeführt.
- Ferner werden in der DE-OS 3,323,153 Amine, insbesondere tert. Amine und Imidazole als besonders geeignete Reaktionsbeschleuniger für spezielle EP/IC-Harze beschrieben, die als zusätzliche Epoxidharzkomponente Polyoxyalkylenglykolpolyglycidylether zur Verbesserung der thermischmechanischen Eigenschaften der Harze aufweisen.
- Weiter sind aus der DE-OS 2,846,123 Cyanessigsäureester und -amide als Härter für Epoxidharze in der Wärme bekannt.
- Nachteilig ist jedoch, dass die Reaktivharzsysteme, die Borhalogenid/Amin-Komplexe als Reaktionsbeschleuniger enthalten, eine schlechte Feuchtigkeitsresistenz aufweisen. Dies führt z.B. für eine Kombination von 3-4 % BF₃/Monoethylamin mit einem Epoxidharz bei 96 % relativer Feuchtigkeit bei 70°C zu einem sehr markanten Anstieg des dielektrischen Verlustfaktors. Ferner können sich durch Hydrolyse der entsprechenden Borhalogenide hochkorrosive Gase wie HCl und HF bilden, was für die Anwendung auf dem Gebiet der Elektrotechnik und Elektronik nachteilig ist.
- Zudem besteht ein Bedürfnis nach EP/IC-Harzsystemen mit Reaktionsbeschleunigern , die bei der Verarbeitungstemperatur einen langsamen Reaktionsverlauf aufweisen, d.h. eine längere Verarbeitungsdauer ermöglichen und auch eine bessere Lagerstabilität zeigen. Ebenfalls wichtig für die Anwendung solcher EP/IC-Harzsysteme auf dem Gebiet der Elektrotechnik und Elektronik ist eine gute Wärmealterungsbeständigkeit.
- Ueberraschend weisen nun Cyanacetamid-Beschleuniger in reaktiven EP/IC-Harzsystemen die gewünschten, vorstehend dargestellten, Eigenschaften auf.

- Die erfindungsgemässen Reaktionsbeschleuniger der Formel I können z.B. nach der in der DE-OS 2,846,123 beschriebenen Weise hergestellt werden.
-
- Als Reaktivharzsystem wird die folgende Basis Formulierung verwendet, wobei die Mengenangaben, wenn nichts anderes angegeben steht in Gewichtsteilen oder Gewichtsprozenten angegeben sind.
Novolak-Epoxidharz (5,7 Aeq./kg) 100 Polypropylenglykoldiglycid (2,55 Aeq./kg) 100 p,p-Diisocyanatodiphenylmethan (7,8 Aeq./kg) 250 Reaktionsbeschleuniger 1/30 Mol/Epoxid aus Beispiel 1 4.2 Quarzmehl W 12 (für gefüllte Harzsysteme) 836 - Die Komponenten Novolak-Epoxidharz, Polypropylenglykoldiglycid und p,p-Diisocyanatodiphenylmethan werden in einem Metallbehälter eingewogen. Das Gemisch wird auf 100°C erwärmt, worauf der Reaktionsbeschleuniger sowie ein Tropfen Glassomax® 580-1501 (Glasorit-Werke, Hamburg) als Entschäumungsmittel zugegeben wird.
Die Reaktionsmischung wird mit einer mechanischen Rührvorrichtung (Motor mit Propeller-Rührer) während 2 bis 3 Min. gerührt und anschliessend während ca. 5 Min. entgast (Pumpenleistung ca. 500 l/Min., ca. 0,1 mbar) und bei ungefähr 80°C in eine auf 100 °C vorgewärmte 3 mm-Form gegossen und während 4 Std. bei 140°C und 16 Std. bei 200°C ausgehärtet.
Nach der Entformung werden Prüfkörper der Dimension 15x10x3 mm herausgeschnitten und zur Erfassung des Gewichtsverlustes bei 180°C herangezogen. - Zur Beurteilung der Wärmealterung werden Reinharzproben während 56 Tagen bei 180°C gelagert und am Ende dieser Zeit der Gewichtsverlust gemessen.
- Der Gewichtsverlust beträgt 1,86 %.
- Hierzu werden gefüllte Formulierungen verwendet. Die Harzkomponenten werden wie unter A) beschrieben eingewogen und auf 100°C erwärmt. Dann wird der auf 100°C vorgeheizte Füllstoff zugegeben. Erst danach wird der Reaktionsbeschleuniger beigefügt. Die Weiterverarbeitung erfolgt gemäss der unter A) angegebenen Methode. Die Messungen zur Bestimmung der Gebrauchsdauer werden nach der Höppler-Kugelfall-Messmethode bei 80°C vorgenommen.
- Die Resultate sind in Tabelle 2 wiedergegeben.
Tabelle 2 Zeit [min] 0 5 10 20 30 34 Viskosität [mPa·s] 15000 15500 16000 18000 18500 19000 - Die Resultate aus Tabelle 2 zeigen deutlich den langsamen Viskositätsaufbau für die mit dem erfindungsgemässen Reaktionsbeschleuniger versetzten Reaktivharzsysteme, wie er im Sinne einer langen Gebrauchsdauer sehr erwünscht ist.
